What is actually going wrong? And what is in $_REQUEST['age'] if you che=

it?

Its preferable to explicitly state where the value comes from, so =
$_GET['age'], $_POST['age'] etc.

You might want to look into a switch statement (I'll assume POST, change=
=
if this isn't the case):
<?php
$age =3D false;
if(isset($_POST['age']){
switch($_POST['age']){
case '0-29':
case '30-60':
case '60+':
$age =3D $_POST['age'];
echo "<p>Your age selection was {$_POST['age']}</p>";
break;
default:
echo '<p style=3D"color:red;">'.htmlspecialchars($_POST['age']).' is =
not =
a valid selection.</p>';
=
}
}
if($age=3D=3D=3Dfalse) echo '<p style=3D"color:red;">You forgot to selec=
t you =
age!</p>';
?>
Or a 'valids' array:
<?php
$valids =3D array('0-29','30-60','60+');
if(isset($_POST['age']) && in_array($_POST['age'],$valids){
echo "<p>Your age selection was {$_POST['age']}</p>"; =
} else {
echo '<p style=3D"color:red;">Please select a valid age.</p>'
}
?>

My new ISP's newsserver sucks. Anyone recommend a good one? Paying for =
quality is certainly an option.
